We are currently witnessing a shift in computer science from classical, closed computer systems to open, interactive systems whose components harness each other's power. This is particularly true in Human-Computer Interaction, where research has shifted from user interfaces for controlling computational processes to large-scale mediated communication tools, such as the Web, and mixed reality environments that foster creativity. In this talk I will explore the notion of _interactive computation_[1] in the context of Human-Computer Interaction. I will emphasize the need to create novel models, tools and interaction techniques that leverage interaction and treat it as a first-class object. I will illustrate this approach with our work at the InSitu lab, in particular instrumental interaction, multi-scale, multi-surface interfaces and reflective, reconfigurable tools.

Speaker Biography
Michel Beaudouin-Lafon is Professor of Computer Science at Université Paris-Sud (France) and director of LRI, the laboratory for computer science joint between Université Paris-Sud and CNRS. With close to 300 faculty, staff and Ph.D. students, LRI is one of the leading French labs in computer science and is internationally recognized in areas including quantum computing, graph theory, software engineering, grid computing, arti?cial intelligence and human-computer interaction.

Michel has worked in human-computer interaction for over 20 years and was elected to the ACM SIGCHI Academy in 2006. His research interests include fundamental aspects of interaction, engineering of interactive systems, computer-supported cooperative work and novel interaction techniques. His current research is conducted in the In Situ group, a joint lab between LRI and INRIA (http://insitu.lri.fr).

Michel founded AFIHM, the Francophone association for human-computer interaction, in 1996 and was a member of the ACM Council and the ACM Publications Board from 2000 to 2007. He has been on numerous international program committees, including as papers chair for ACM CHI 2001 and program chair for ACM UIST in 2008. He chaired the ACM UIST conference in 2002 and the E-CSCW conference in 2005.
